Subject: [PATCH] Reduce unnecessary History updates on order saving.

if store-id stored into model data array, the whole history collection of an order will get updated.

to reduce unnecessary mysql updates, i've used the store id directly from the order object.

fyi: all changes into a model data array will set a flag (save me again).
